Exchange / Outlook 2007 Upgrade from 2003 - Assigned Tasks updates lose Color Category Information


I am upgrading our Exchange 2003 environment to 2007. All clients are running Outlook 2007, regardless of which Exchange Server their Mailbox resides on.

After moving a user from Exchange 2003 to Exchange 2007, any assigned Tasks that they flag with the new "color categories" have a problem.

Let's say I create a Task Request, and send the request to User B. Whenever User B sends any update to the task, including simply accepting the Task Request, the item becomes uncategorized in my Task List. So basically I have to re-categorize any assigned tasks whever anybody sends an update for that task.

Apparently this behavior is only occurring with users who have been transitioned to Exchange 2007, so it isn't an Outlook 2007 thing...the clients have been doing this with Outlook 2007 and Exchange 2003 for months with no problems.

Any ideas would be greatly appreciated.

Any help would be appreciated.

You need to make sure that all the clients have the same name/colour combination in Categories, for example, if you have "Red Category" and someone else has renamed the red category to "Requests", outlook will look at your categories and see that you don't have a "Requests" category defined, hence the uncategorised task.

Okay, but this was not an issue until a mailbox for a particular user was moved to Exchange 2007.

This was not an issue between two users on Exchange 2003...only when one or the other's messages are going through Exchange 2007...so I would have to assume that it's an Exchange issue.

Plus, everybody's categories are completely different according to their preferences, so what you are suggesting is next to impossible to maintain, unless there is a central repository that combines everybody's categories.

I can't tell everybody in the company to manually match evberybody else's categories every time they change.

I went with the Exchange 2007 angle first, since it only started happening after transitioning a user to the new Mailbox.

Running the cmdlet "Set-TransportConfig -ClearCategories $False" in the Exchange Management shell did the trick.

Works like a champ...nothing needed to be done on the Outlook 2007 client at all.

Thanks a heap for the help!
